ROOF.

SPECIFICATION forming part of Letters Patent No. 274,265, dated MarchApplication filed August 21, 1882. (No model.)

To all whom it may concern Be it known that I, NATHANIEL BUTTER- FIELD,a citizen of the United States, residing at Monroe, in the county ofGreen and State of Wisconsin, have invented a new and useful PortableRoot for Ricksand Sheds, of which the following is a specification,reference being had to the accompanying drawings, forming a partthereof.

The object of my invention is to furnish a cheap, easily-constructed,and portable rooffor the protection of hay and grain and to be used asshedding. This object I attain by constructing after the methodillustrated in the accompanying drawings, in Which- Figure l is ahorizontal under side view, showing details of construction. Fig. 2 is ain use.

The roof is made in sections, each section being in two parts,joined atthe center by passinga boltor othersuitable device through in Fig. 1.Each half-section is made of three or more rafters and two cross-ribs, GG, in Fig. 1, as a frame, and covered with lap-boarding G. At F ropes orwires are attached, to

which weights are suspended, and by this means. the roof is kept inposition as the stack settles. At E is a hole throughthe rafter, throughwhich the roof may be fastened to posts in making temporary sheds. At Done of the boards overlaps, so that when the roof is at an angle of fromthirty degrees to forty-five degrees the roof is tight. The ribs ()0,to-

gether with the rafters, separate the roof from the hay or tion ofair.

I am aware that hinged or jointed roofs prograin, and so allow a freecirculavided with anchoring devices are not new, and
